A man has told the High Court in Aberdeen that he was kidnapped from outside his sister's home in Inverness by four men posing as police officers.
Noor Miah, 29, said the men threatened to kill him and his family if he did not tell them where his brother was.
Mir Habib Sufain, 35, Safiul Alam, 38, Zuhel Rahman Ashuk, 32, and Imran Raja, 30, are accused of assault and alleged abduction.
All four men deny the charges. The case continues.
Giving evidence, Mr Miah said he was approached in August last year by a man claiming to be a police officer before another man grabbed him and lifted him into the seven-seater Vauxhall Zafira.
Mr Miah said he was blindfolded but that the blindfold was removed when the car came to a stop five minutes later.
Advocate depute Sheena Fraser asked him: "How are you feeling at this point?"
Mr Miah said: "They told me they will kill me and I was very upset."
The four men are accused of falsely representing themselves as police officers, seizing hold of Mr Miah and forcing him into the rear of a vehicle.
They are further accused of abducting Mr Miah, conveying him against his will on various streets in Inverness, and during the course of the journey threatening to stab and kill him.
They are also charged with threatening to kill members of his family, demanding he tell them the whereabouts of his brother, blindfolding him with a pair of trousers, or similar item, and pinning him down in the rear of the vehicle and repeatedly slap and punch him on the head.
All the charges were denied.
UPDATE: 8 February 2011. On Thursday 3 February, the jury returned a not proven verdict to the charges against all four men.
